(Main)Bitumen and bituminous binders - Measurement of density and specific gravity - Capillary-stoppered pyknometer method
Bitumen and bituminous binders - Measurement of density and specific gravity - Capillary-stoppered pyknometer method
This European standard specifies a procedure for determining the specific gravity and density of bituminous binders at (25,0 ± 0,2) °C using the capillary-stoppered pyknometer method. Emulsions are excluded from the scope of this method.
NOTE 1 This method can also be used for other hydrocarbon binders, for bituminous binders from other sources, e.g. recovered from asphalt or after hardening and for bituminous binders containing filler. However, a lower precision is to be expected.
NOTE 2 This test method may be performed at other temperatures (i.e. 15 °C). When doing so, the density values of water and isopropanol should be determined.
The pyknometer method shall be used as a reference method for determining the specific gravity and density of bituminous binders.
WARNING - Use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Bitumen und bitumenhaltige Bindemittel - Messung der Dichte und der relativen Dichte - Pyknometerverfahren mit Kapillarstopfen
Diese Europäische Norm legt ein Verfahren zur Bestimmung der relativen Dichte und der Dichte von bitumenhaltigen
Bindemitteln bei (25,0 ± 0,2) °C mit Hilfe des Pyknometerverfahrens mit Kapillarstopfen fest. Dieses
Verfahren gilt nicht für Emulsionen.
ANMERKUNG 1 Dieses Verfahren kann auch auf andere Kohlenwasserstoff-Bindemittel, auf Bindemittel aus anderen
Quellen, z. B. aus Asphalt rückgewonnene oder bereits verhärtete Bindemittel, und auf bitumenhaltige Bindemittel, die
Füller enthalten, angewendet werden. Jedoch muss eine niedrigere Präzision erwartet werden.
ANMERKUNG 2 Dieses Prüfverfahren kann bei anderen Temperaturen durchgeführt werden (d. h. 15 °C). In diesem
Fall sollten die Dichtewerte von Wasser und Isopropanol bestimmt werden.
Für die Bestimmung der volumenbezogenen Masse und der Dichte von bitumenhaltigen Bindemitteln muss
das Pyknometerverfahren als Referenzverfahren herangezogen werden.
WARNUNG — Die Anwendung dieser Norm kann den Umgang mit gefährlichen Substanzen und
Ausrüstungsteilen und die Ausführung gefährlicher Arbeitsgänge einschließen. Diese Norm erhebt
nicht den Anspruch, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Es
liegt in der Verantwortung des Anwenders dieser Norm, geeignete Verhaltensregeln zur Sicherheit
und Gesundheit festzulegen und die Anwendbarkeit einschränkender Vorschriften vor der Anwendung
zu bestimmen.
Bitumes et liants bitumineux - Mesure de la masse volumique et de la densité - Méthode du pycnomètre à bouchon capillaire
La présente Norme européenne prescrit une procédure pour déterminer la densité et la masse volumique des liants
bitumineux à (25,0 ± 0,2) °C suivant la méthode du pycnomètre à bouchon capillaire. Les émulsions sont exclues du
domaine d’application de cette méthode.
NOTE 1 Cette méthode peut aussi être utilisée pour d’autres liants hydrocarbonés, pour des liants bitumineux d’autres
provenances, par exemple ceux obtenus à partir d’enrobés ou après durcissement, et pour des liants contenant des fines.
Cependant, une précision plus faible est obtenue avec ces constituants.
NOTE 2 La présente méthode d’essai peut être effectuée à d’autres températures (par exemple 15 °C). Dans ce cas, il
convient de rechercher les valeurs des masses volumiques de l’eau et de l’isopropanol dans ces conditions.
La méthode du pycnomètre doit être utilisée comme méthode de référence pour la détermination de la densité et de
la masse volumique des liants bitumineux.
ATTENTION — L'utilisation de la présente Norme européenne peut impliquer le recours à de produits, des
opérations et des équipements à caractères dangereux. La présente Norme européenne n'est pas censée
aborder tous les problèmes de sécurité concernés par son usage. Il est de la responsabilité de l'utilisateur
de consulter et d'établir des règles de sécurité et d'hygiène appropriées et de déterminer l'applicabilité des
restrictions réglementaires avant utilisation.

Density, , is calculated from specific gravity, d, of the bituminous binder. NOTE 2 Density is used for converting volumes to mass as required by other standards, applications and in sale transactions. 3.2 specific gravity (d) ratio of density of the bituminous binder, , and density of a test liquid, T, measured under the same conditions, at 25,0 °C Tdρρ=25/25 (1) SIST EN 15326:2007+A1:2009
EN 15326:2007+A1:2009 (E) 5 4 Principle Masses of equal volumes of bituminous sample and of test liquid are compared. Equal volumes are ensured by the pyknometer being filled so as to overflow when placed in a bath at the test temperature until thermal equilibrium is reached (approximately 30 min). The calibrated pyknometer is filled approximately three quarters of its capacity with the bituminous binder to be tested and weighed with the stopper. The pyknometer is filled with a test liquid and weighed again. From the different masses, specific gravity and density shall be calculated. 5 Reagents 5.1 Test liquids Freshly boiled and cooled distilled water or deionized water shall be used to fill the pyknometer, the low-form beaker (6.6) and the waterbath. For testing petroleum cut-back and fluxed bitumen for which specific gravity at 25 °C is assumed to be lower than 1, isopropanol (propan-2-ol) with a density of (782,7 ± 0,1 ) kg/m3 at 25 °C shall be used. 5.2 Solvents Appropriate solvents are required to clean the equipment used. 6 Apparatus 6.1 Pyknometer Glass, consisting of a conical or cylindrical vessel carefully ground to receive an accurately fitting glass stopper. The stoppered pyknometer shall have a capacity of (25 ± 2) cm3, and shall weigh not more than 40 g. The wide-mouth (Hubbard) form of pyknometer may be used as detailed in ISO 3507. In case larger samples are available, a larger Hubard pyknometer with a 50 ml capacity may be used also detailed in ISO 3507; masses should be determined with the same accuracy. The upper part of the stopper shall be smooth and perfectly flat. Its lower part shall be concave to allow air bubbles to easily escape through the opening. The concave part shall have a height of (5 ± 1) mm in the middle. An example of suitable pyknometer is illustrated in Figure 1. SIST EN 15326:2007+A1:2009

The appropriate temperature shall be adapted to the type of binder tested. 6.6 Low-form beaker Capacity of 600 ml is convenient. 7 Procedure 7.1 General Samples shall be taken and prepared according to EN 58 and EN 12594.
